LOCK-STRIKE.

SPECIFICATION forming part of Letters Patent No. 232,954, dated October 5, 1880. Application filed Juno 1:2, 1880. (Model.)

To all whom fit may coaccmz:

Be it known that I, HENRY FELLoWs, of Bloomington, in the county of Monroe and State of Indiana, have invented a new and faluable Improvement in Catches forBolts and Latches; and I do hereby declare that the following is a full, clear, and exact description of the construction and operation of the same, reference being had to the annexeddrawing, makinga part of this specification, and to the letters and figures of reference marked thereon.

The drawing is a representation of a horizontal section of a door and casing, showing my im proved catch applied.

This in vention has relation to improvements in catches for lock-bolts and latches.

The object of the invention is, niainly, to secure the engagement of the spring-bolt with the catch and at the same time press the door against the jainb, thus preventing rattling and excluding cold air.

The nature of the invention will be hereinafter fully set forth.

In the annexed l1a\\"ing, the letter A designatcs the door-case, and B the door, hinged' thereto and bearing, when closed, on a shoulder, a, of said frame.

O indicates the lock secured to the door, and designed to e11gage,with its spring-bolt b, the catch D. This is of box form, and the bolt Z) engages thercwith by coming in contact with its beveled face d on its adj acent edge. VVithin the catch is an inclined bearing, e, beveled oppositely to the face d of the bolt, the effect of which, in connection with the said bolt, is as follows: The door closing` only when the bolt is thrust in the lock past the edge of the catch, and being engaged with the same by the relows that the end of said bolt comes in contact with the inclined bearing c, Whicl|,acting as a. wedge, presses the door inward against its bearing strip or shoulder a, and both prerents rattling and the ad mission of air into the room.

It is well known that when the lock and catch are close together or in contact the bolt fails to engage the catch Very often, and the 'door is really open when supposed to be shut. To correct this defect the lock must be set back from the catch, or the reverse, which allows the door to rattle. The inclined bearing correets this defeet, and in addition forces the door against its bearing-strip and excludes air.

What I claiin as new, and desire to secure by Letters Patent, is-

The combination, with a door-case and the catch D, having the beveled or inclined bearing e within the said catch, of the door B and the lock O, having the spring-bolt Z), engaging said bearing automatically, snbstantially as specitied.

In testimony that I claim the above I have hereunto subscribed iny name in the presence of two witnesses.
